Currently doing a side-by-side build with someone by email, using the method (by our very own Mac50l) found at https://canterburyseakayak.wordpress.co ... -your-own/, thought I'd throw it up here as well.
I have a rack of blanks all precut - I like to do them in batches so I can mix and match the offcuts to give contrasting spines so I apologise for you joining the program in progress
Can whack one of these out in a weekend from first touch of the saw in summer due to the higher temps giving a faster cure of the epoxy, in winter it takes a bit longer.

The two halves of one side spine (offcut split in half) at top with loom below - Note centre lines.

I like to put the dressed sides together as my cuts are usually fairly rough in texture (which equates to more glue)

Tips lined up on centre at one end

Mark the position of the pieces on the main paddle to avoid excess, or not enough glue coverage
Also mark the edge of the loom on the underside of the offcuts (at bottom), again to avoid glue going everywhere.
Epiglue, when cured, is bloody hard to plane/sand/grind and very easy to lose the soft cedar either side.

Epiglue, medium size pot will do around 4-6 paddles easy
Pans for mixing glue
Iceblock sticks (break one in half, each half to one glue component, then gets thrown. Use a new stick for mix and application)
Pie dishes (or similar)
Gloves (or you will get glue all over your fingers)
$5 Clamps and packing pieces to avoid bruising the wood.

Even coverage on all mating faces. On with a feather, off with a knife as my Gran used to say.

Nice joint with just a hint of glue being squeezed out - Note the gluey fingerprint.

Once positioned, lay gladwrap over it, then put the PVC clamps on, checking alignment.
Then packing pieces and clamp it down. Note lump of lead in lieu of clamp. Have also used fishfinder and car batteries as well as tins of paint in the past.

A few things about the laminated paddle. It saves wasting half the timber you buy if using a 2x4 chunk. This also means less work shaping things. You can put the laminates back in the opposite direction and get a stiffer, stronger paddle. A bit like plywood except in this case all of the grain is going the same way or opposite way and not crossways.

Took the blank into work today.
Just under an hour with the spokeshave to rough shape it ready for the sanding.
It weighed in at 1290g here

This shows the offcuts making the spine overhanging the loom (in centre)

Image is foreshortened here, but can see some funky grain that materialised - Will likely set this one adrift in the Bay for someone to find washed up.

Spokeshave finish - amazing tools.

500 grams of shavings....

Would have liked the spines to have been longer, but the curly grain has all but condemned this one for serious paddling.
They will be thinned down at the shoulder, but conflicting grain directions means it'll be a sanding job

With rough shaping completed and ready for sanding, now 60% of the initial weight

I am trying this project with advice from HLD. Will post a few ham fisted photos of my progress later which should give hope to all in doubt of their skills. Have rushed ahead on a couple of steps which did not help but am getting the idea and the next one should make more sense. Any goof ups are all mine and nothing to do with great advice I've received so far. I'm new enough at anything like this to have asked what a plane saw was and the spokeshave is still a computer image but hope to get one for the next effort. Am using a sur-form plane device now and have a garage half full of shavings due to using a rough sawn bit of timber and general lack of expertise. None of this has put me off and I'm sure this one will have value even if it is only as a training exercise. Will go the photo battle later today to show what I've done.
Thanks to HLD as otherwise I would be looking at buying a wood stove for this project to fit into.
Where do find such a nice weighing machine??

Time for photos when I can figure out this system. Scales will wait for a time but I'm sure I will be on the heavy side so can always weight loss if required.

Rough outline of paddle, off cuts split and one side glued.

Clamped, weighted and magic chants uttered while the wait goes on.Ready to attack with sur-form

Before sur-form effort. Still a long way to go.

Clamps from PVC pipe. Need to make some wider and don't reccomend skill saw. Used hack saw to keep from breaking too many rings. also need a few more clamps. Could use more expertise also.

Now to continue my efforts and prepare for a non museum piece. Grain ran away like HLD's last one and one end of blade has a small spoon feature that will be hard to address but maight make turning the yak easier on that side.
Thanks again to HLD and welcome all advice.

Clamps - good to see you are making them. Cutting - a handsaw or tenon saw (the short one with a stiffener along the top edge). Rotate the pipe as you cut. At he Shed we have a full range of power tools. Unless it is a long cut (plywood panel or some such) I'll pick up a handsaw. Maybe it comes from having (what's left) grey hair.

Spooned end - I have one paddle both ends and on both sides are slightly spooned at the ends. Works OK. It got that way through trying to use a jig and router. Cut set too deep. It does have thicker (than the blade) kwila tips fitted.

Just looked at this site again. My last 4 Western Red Cedar boards at about 90mm x 20mm x 2400 were from a glass and timber place in Matamata. If you let me know I can find the address for you. I’ve used 2 for paddles and now with lockdown have started 2 more paddles.
